I just did the opposite and removed my Corsa for a 3" B&B w/ resonator.
For the moment, I don't have cats on the B&B, so it is a bit loud.
The Corsa was definetly quieter on the freeway while cruising at low RPM.
I like the tone of the B&B better at idle and when getting on the throttle.
Corsa had a raspy bark as opposed to the rumble of the B&B.
It really comes down to personal preferance, as to which exhaust has the better sound.
I do expect my B&B to tone down a bit when I get the new set of cats installed.
At which point it should be perfect (for my ears).
If one was mainly concerrned with quietness the 2.5" B&B w/ resonator [aka Touring] would be a good choice.
Comparing a 3" B&B to a 2.5" Corsa is apples to oranges.
I will say that Rob's car is surprizingly quiet.
Perhaps that's more of an LS2 [mellow truck engine] thing than an exhaust thing.
